Abstract

(57) [Summary] [Purpose] The objective is to provide a weak instrument for stringed instruments that does not hinder the performance and has a large weakening effect. [Structure] A weak instrument for stringed instruments, in which a knob that is used to attach an object that does not vibrate to the side of a stringed instrument piece is integrated.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weak instrument that can be used in many stringed instruments having a piece.

[0002]

[Prior art]

 Traditionally, the violins of the string instruments of the violin genre are the ones in which the plastic, rubber, wire, etc. are bent, and they are inserted from above. This has a structure that can be attached and detached instantaneously in response to a request to change it in the middle of the song in order to change the musical expression. Therefore, 1, there is little weak sound effect. 2. In the violin and viola, the contact position between the bow and the string cannot be seen due to the weak instrument sandwiched between the pieces, and normal performance cannot be performed. There was a problem such as.

[0003]

[Problems to be solved by the device]

 The idea is to improve the effect of the silencer, reduce the volume as much as possible, reduce the volume to the extent that it does not disturb people in the neighborhood at night, and avoid the above-mentioned performance problems. is there.

[0004]

[Means for Solving the Problems]

 The violin is a stringed instrument. The principle of sounding is to vibrate the strings by means of striking with a bow, striking with a finger, etc., and transmitting the vibrations to the body through the bridge, causing resonance in the entire resonance box and producing sound. Therefore, in a musical instrument of such a structure, the piece easily vibrates, and a material and a shape with a high speed of transmission of vibration, that is, a good response have been demanded. However, in the present invention, conversely, it is difficult to vibrate, and an object that absorbs vibration is brought into close contact with the side surface of the piece to absorb the vibration, thereby reducing the sound.

[0005]

[Action]

 As described above, in order to absorb a large amount of vibration of the piece, it is preferable to use an object that has the largest joint area between the heavy and heavy object and the largest piece. However, there is a limit to the size that can be attached to a piece such as a conventional low-pitched sound device that slides from the top of a piece, and you cannot see the important part where the strings and the bow come into contact during performance. Therefore, since there is a large area on the side of the piece (the surface in front of the piece and the back surface on the opposite side in the playing state), there is a large space that does not interfere with the performance, so use that. That is, by attaching the vibration-absorbing object to the side surface of the top and bringing them into close contact with each other, the noise reduction effect can be further enhanced.

[0006]

【Example】

 FIG. 1 shows an example in which a conventional typical silencer is attached. Reference numeral 1 is a conventional typical silencer 2, is a piece 3, is a string 4, is a main body 5, and is a cross section of a bow. During the performance, the position of the eyes is at the point A, and the bow 5 is playing at the point B of the string 3. When the sound absorber 1 is attached to it, the line of sight is obstructed and the point B cannot be seen. FIG. 2 is a perspective view showing an example of the silencer of the present invention. Reference numeral 11 denotes a weight 12 having a predetermined weight, reference numeral 13 denotes a holding component for holding the weight 11, and reference numeral 13 denotes a knob for closely holding the holding component 12 on the piece 14. The silencer of the present invention is constituted by the symbols 11, 12, and 13 described above. FIG. 3 is a perspective view of the sound absorber of the present invention attached to a violin body. 14 is a piece 15, is a string 16, and is a violin body. The knob 13 is rotated inward from the right and left, respectively, and is brought into close contact with the tapered surface having a trapezoidal cross section. That is, it is possible to absorb the vibration of the piece 15 and reduce the noise.

[0007]

[Effect of device]

 Since the silencer of this invention is designed to be attached to the side of the piece, a heavy and large object can be attached in a large space in front of and behind the piece, and the sound-deadening effect can be increased accordingly. In addition, there is nothing that pops out above the piece, so there is no problem in playing. You can freely change the size and weight of the weight to set the effect of weak sound.
